Energy Analysis – Heat Load Calculation
Heat Load Calculations has become more of a science that in the past when the idea was put in the biggest furnace that I can put in the closet that the architect gave they must have made it that big for a reason. “Rule of Thumb” was the way it was done, unless it was a commercial building and then some mechanical engineer had a mechanical plan that was designed to go through load bearing points or in the middle of a vaulted ceiling. This resulted in poor energy efficiently and loss of performance.
Advance Concept has solved those problems by bring the mechanical engineer in-house to work as part of the team in the design stage of the building along with the journeymen that will install the system. Though our 3D modeling all parts of the building and HVAC system can work together to provide the most energy-efficient system for space and the budget.
There are many parts that go into designing the right HVAC for your building whether it is a new construction, remodel, or a replacement of an existing system. This items include
- Sun Exposure
- orientation of the building
- Outdoor landscaping
- Size of each room and placement in the building
- Room purpose (I.E. bedroom vs kitchen vs food storage room)
- Roof type
- Siding type
- Indoor finish type
- Floor type
- Insulation type and R value
- Building equipment (I.E. stoves, ovens, fryers, servers, ) that change the room environment
Once all of these factors are accounted for we are able to design and build a system for that building.
Testing and Balancing
Once a system is installed it needs to be “tested and balanced” to get maxim efficiency. Most people think that the register needs to be opened all the way, this is not the case as the system works better with some minor “back pressure” this allows the rooms that are closer to the unit to be at the same climate as the ones at the end of the duct run. Also this allows the air to be heated or cooled more which helps with the unit efficiency.
